gidium , belongs to the same subgenus. 
784. Baucus scariosus Raf. stem grooved 
foliose retrose pilose, leaves 2-3pinnate, seg- 
ments lanceolate acuminate or cuspidate ; invo- 
lucres 6-8 foliose Mpinnate , partial unequal 
lanceolate white scariose, longer than flowers, 
some trifid.— Annual or biennal root not odor- 
ous, leaves long and narrow, nerved.— Var. sim- 
plex simple stem pedal, a single umbel, hardly 
hispid— Var. ramosus branched hirsute, invo- 
lucres hardly bipinnate, very long segments 
sometimes trifid. Found by myself in the glades 
of Pennsylv v . autumnal, petals apparently not 
radiate, thus a Gingidium also. 
785. Baucus brevicaulis R. Scabrous, stem 
nearly naked, lower leaves nearly as long tri- 
pinnate, segments confluent oblong bifid inner or- 
nate ; involucres mostly trifid base scariose on 
the margin, linear elongate, partial linear and 
trifid 1 shorter than flowers, petals radiate* — A 
singular sp. found in hills of Pennsylvania and 
near Philadelphia, with ample ^leaves 6 to 8 
inches long nearly as long as the. stem, with 
broad segments, roots . biennial hardly odorous 
branched. 
786. Baucus wumcaulis Raf. smooth; sub™ 
scapose, scape naked grooved, leaves radical 
bipinnate segments linear Jaciniate cuspidate - ; 
umbel lax, involucres 3-5fid setaceous, partial 
linear equal to flowers, margin scariose, petals 
radiate — found with the last, perhaps a devia- 
tion, but it has another deviation var. purnila 
only 3 inches high, leaves larger than umbel 
quite linear— while the nudicaulis is 6 to 8 
inches high, with short leaves 3 inches long, root 
white tapering slender.
